Intel® Core™ X-series Processors (4-core) Chapter 1 Memory configurations You may install 2 GB, 4 GB, 8 GB and 16 GB unbuffered and non‑ECC DDR4 DIMMs into the DIMM sockets. • For Intel® Core™ X-Series Processors (4-core), you may install varying memory sizes in Channel C and Channel D. The system maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation. • For Intel® Core™ X-Series Processors (6-core or above), you may install varying memory sizes in Channel A, Channel B, Channel C, and Channel D. The system maps the total size of the lower-sized channel for the quad-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation. • The default memory operation frequency is dependent on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value. • For system stability, use a more efficient memory cooling system to support a full memory load (8 DIMMs) or overclocking condition. • Always install the DIMMS with the same CAS Latency. For an optimum compatibility, we recommend that you install memory modules of the same version or data code (D/C) from the same vendor. Check with the vendor to get the correct memory modules. • Visit the ASUS website for the latest QVL. 1-6 Chapter 1: Product Introduction
